IG–23 IGNITION SYSTEM – (2JZ–GTE) SPARK PLUG CLEANER IG0152 6. CLEAN SPARK PLUGS If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner. Air pressure: Below 588 kPa (6 kgf/cm2, 85 psi) Duration: 20 seconds or less HINT: If there are traces of oil, remove it with gasoline before using the spark plug cleaner. 7. REINSTALL SPARK PLUGS Torque: 18 N·m (180 kgf·cm, 13 ft·lbf) 8. REINSTALL IGNITION COILS ASSEMBLIES (See ignition coils installation) IGNITION COIL INSPECTION NOTICE: "Cold" and "Hot" in the following sentences express the temperature of the coils themselves. "Cold" is from –10°C (14°F) to 50°C (122°F) and "Hot" is from 50°C (122°F) to 100°C (212°F). 1. REMOVE NO.3 TIMING BELT COVER 2. DISCONNECT IGNITION COIL CONNECTORS Ohmmeter F11795 3. INSPECT PRIMARY COIL RESISTANCE Using an ohmmeter, measure the resistance between the positive (+) and negative (–) terminals. Primary coil resistance: Cold 0.54 – 0.84 Ω Hot 0.68 – 0.98 Ω If the resistance is not as specified, replace the ignition coil. 4. RECONNECT IGNITION COIL CONNECTORS 5. REINSTALL NO.3 TIMING BELT COVER
